WRENCH.

SPECIFICATION forming part of Letters Patent No. 732,126, dated June 30, 1903. Application led April 12, 1902- Serial No. 102,630. (No model) To all whom, t mary concern.:

Beit known that I, JAMES H. SHEPHERD, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Wrenches; and I do declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which simiiar letters of reference indicate corresponding parts in all the figures.

My invention relates to a class of wrenches in which the adjustable jaw can be locked and released very readily and at any point along the main shank of the wrench.

The objects of my invention are to provide a wrench that can be quickly adjusted to hold any-sized nut and which can be just as readily released and changed from one nut to another of a different size, one in which all parts are strong and durable and will not bend and get out of line, one in which the entire construction contains but very few parts and in which the parts are interchangeable and can be replaced if damaged or broken'.

I am aware that wrenches have been patented heretofore which embody certain features shown in my application, which will be hereinafter fully specified and disclairned.

In further explaining the nature and objects of my invention Prefer now to the drawings, in which- Figure l is an elevation of my improved wrench. Fig. 2 is an elevation of the -handle and shank, showing the adjustable jaw and locking device in central cross-section. Fig. 3 is a View of the adjustable jaw. Fig. 4 is an elevation of the wrench as placed upon a nut. Fig. 5 shows the adjustable jaw tightened against the nut. Fig. 6 is a cross-sec- Fig. 7 is a central crosssection of the locking-nut.

In further reference to the drawings, A represents the shank ofthe wrench, which is provided with an ordinary fixed jaw, (indicated by A.) The handle A2 is ot' any ordinary construction, as I do not claim anything thereon. It is provided with a ferrule at the npper end, (indicated by A3.) The shank A extends through the handle A2 and through the ferrule A3, the end of which is provided with an external thread on which is placed an internally-threaded nut, (represented by A4.) The shank A is provided with beveled grooves on each side, (represented by A5 and Ain Fig. 6 of the drawings.) The Shank is oval in construction, as illustrated. It is provided with threads on the ends of the oval. These threads are represented by A7 and AB. They are mutilated and instead of being as ordinary threads are constructed straight,as illustrated, and do not extend over the beveled grooves, but simply over the part of theshank which constitutes the ends ot' the oval.

rlhe adjustable jaw is represented `by B and is provided with an oval aperture having beveled flanges contoured to fit the beveled depressions in the sides of the shank A. The lower part of the adjustable jaw is provided with an external thread (represented by B) fully illustrated in Fig. 3 of the drawings. It also has a cylindrical extension (indicated by B2) which is provided with a circular flange B3.

C represents the locking-nut, which is provided with straight mutilated threads similar to those provided on the shank and are adapted to mesh with those provided on the shank. The length of the threads provided in this lock-nut C are equal to the space between the threads on the shank or to the width of the beveled grooves on the sides of the shank, and when the said locking-nut is released the threaded part of the said nut can readily be moved upward and downward as the threads in the nut travel in the grooved plain parts of the said shank. The inner upper part of the said lock-nut is provided with a recess or depression, (represented by C' in Fig. 7 of the drawings.) Into this recessed portion operates the cylindrical part B2 of the adjustable jaw B and also the collar B2. A circular collar (indicated by C2) is secured within the depressed portion of the locking-nut C and operates around the cylindrical part B2 of the adjustable jaw B between the collar B3 and the threaded portion B, as fully illustrated in Fig. 2 of the drawings.

D represents an adjusting-nut which is provided with internal threads adapted to mesh with the external threads B', provided IOO on thev adjustable jaw B. This adjustingnut D provides means for setting the adjustable jaw securely against the nut, as illustrated in Fig. 5 of the drawings, and provides e'fcient means for regulating the space between the fixed jaw and the adjustable jaw, as illustrated. The termination ofthe external thread B' is squarecut, as illustrated in Fig.

The internal thread provided in the adjusting-nut D is similar, providing a rigid stopping-point for the said adjusting-nut, which will prevent it from becoming tight, as would be the case were it otherwise coustructed.

The successful operation of the wrench will be manifestly as follows: The adjusting-nut D is screwed up against the shoulder of the adjustable jaw. The locking-nut is pushed up against the adjusting-n ut, as illustrated in Figs. l and 4 of the drawings. The lockingnut is turned in a position bringing the threaded parts in line with the beveled grooves provided in the sides of the shank and is moved upward until the adjustable jaw comes in as close proximity to the uut as possible, when the locking-nut is given a turn to the right, meshing the inner threads with the threads provided on the shank, and the space intervening between the adjustable jaw and the nut is readily taken up by givingthe adjustable nut several turns to the right, or in the same direction as the locking-nut was turned, bringing the fixed jaw and the adjustable jaw firmly against the sides of the nut, as illustrated in Fig. 5 of the drawings. When desiring torelease the wrench,

the simple operation of turning the lockingnut to the left or of giving the adjusting-nut a slight turn to the'left very readily releases the adjustable jaw from the nut.

Having thus described the nature and objects of my invention, what I claim as new,

and desire to secure by Letters Patent of the United States, is-

In a wrench, the shank provided with a suitable handle, the beveled grooves or depressions provided in the sides of said shank, the mutilated threads provided on the said shank, the fixed jaw secured to the said shank, the adjustable jaw provided with an opening adapted to encircle the said shank having beveled anges adapted to t in the beveled depressions or slots provided in the sides of the said shank, the threaded extension provided on said adjustable jaw, the cylindrical part provided with a circular collar forming a part of said adjustable jaw, the lockingnut, the mutilated threads provided in said locking-nut adapted to mesh with the threads provided on the said shank, the recessed or depressed portion of said locking-nut, the circular band or collar provided around the inner circumference of said recessed or depressed portion, the said collar adapted to operate in the space provided between the circular collar on the adjustable jaw, andthe external threads on the said adjustable jaw adapted to attach the said locking-nut to the said adjustable jaw and to allow sufficient means for the upward movement of the said adjustable jaw after the said locking-'nut has been set, the adjusting-nut provided with internal threads adapted to mesh into the external threads provided on the adjustable jaw adapted to provide means for adjusting the said adjustable jaw after the said locking-nut has been set or locked.

In testimony that I claim the foregoing as my own I hereunto subscribe my name in the presence of two witnesses.

JAMES H. SHEPHERD.
